FEL_spectrum | R Documentation |
Calculate values by means of a nth degree polynomial from user-supplied constants (for example from a lamp calibration certificate).
FEL_spectrum(w.length, k = photobiology::FEL.BN.9101.165, fill = NA_real_)
w.length |
numeric vector of wavelengths (nm) for output |
k |
a numeric vector with n constants for the function |
fill |
if NA, no extrapolation is done, and NA is returned for wavelengths outside the range 250 nm to 900 nm. If NULL then the tails are deleted. If 0 then the tails are set to zero, etc. NA is default. |
a dataframe with four numeric vectors with wavelength values (w.length), energy and photon irradiance (s.e.irrad, s.q.irrad) depending on the argument passed to unit.out (s.irrad).
This is function is valid for wavelengths in the range 250 nm to 900 nm, for wavelengths outside this range NAs are returned.

FEL_spectrum(250:900)
